The Indian security researcher, Shubham Upadhyay with online handle Cyb3R_Shubh4M, has discovered a persistent cross site scripting vulnerability in eBay site.

In an email sent to Xssed.com, researcher explained the details of vulnerability. In order to exploit the vulnerability, attackers would need a seller account.Once login to seller account on eBay, the attacker would create a listing for sale where he put the XSS exploit code.

At the time of writing , the vulnerability is unfixed . Here is the page where he injected his code:

All of them are reflected XSS Vulnerability. Cyber criminals can exploit these vulnerability for their malicious purpose. They can lure victims into clicking the crafted url that can redirect user to phishing or malware sites.

For example , injecting the following code will redirect user to Google from the vulnerable site:

<script>document.location="http://www.google.com"</script>

Hackers can replace the google.com with malicious url and redirect user to malware page.

The Hacker group called as 'The Wiki Boat Brazil' has discovered three critical vulnerabilities in the official websites of U.S Department of Transportation(dot.gov).

Cross-Site Request Forgery (CSRF) is an attack that tricks the victim into loading a page that contains a malicious request to the server.

The site found to be vulnerable to Cross-site request forgery(CSRF) attack. The hackers provided us the POC for the CSRF attack. This vulnerability allows attackers CSRF to change user to admin , if admin user click the specially-crafted link .

They've also discovered SQL Injection vulnerability in the ITS Deployment Statistics sub domain of U.S. Department of Transportation (www.itsdeployment.its.dot.gov).

Hi, I've discovered a persistent cross site scripting vulnerability in 160by2 website, a popular site used for sending SMS.

Today, while i'm sending message to one of my friend from 160by2, My Hacker mind started to work (after long time). I insert a script instead of message. Successfully , the message has been sent to the receiver.

The inserted script:
<script>alert("BreakTheSec")</script>

At the same time, 160by2 displayed the message send by me in the Sent Box. Yeah, inserted-script is being executed and displayed the popup.

Whenever i visit the Sent box, the popup is being displayed. In fact, the popup is being displayed in the main page also because of "LAST 5 MESSAGES SUMMARY" section in the home page.

I consider the risk level of this vulnerability as very very low because it only work when you logged in. So, it won't help attackers to target victims.

A security researcher, Rafay Baloch, has discovered Cross site scripting vulnerability in the StumbleUpon , One of the famous social bookmarking website with alexa rank of 149.

"Few days before, while i was hunting for vulnerabilities inside stumbleupon.com," Rafay said in his blog post. "Fiddler helped me obtain a non persistent XSS vulnerability inside stumbleupon"

He send notification about the vulnerability to StumbleUpon, however there is no response from other side.

"For security reasons i cannot disclose the URL and parameters for the injection, I hope stumbleupon fixes the vulnerability pretty soon." researcher said.

At the time of writing, the vulnerability is not patched and we are able to exploit the vulnerability. In fact, i inject a redirection code that successfully redirects me to the given url. So , an attacker can exploit this vulnerability for launching social engineering attack and redirect user to malicious site. Also it is possible to hijack session that allows attacker to take control of your stumble upon account.

Few days back, Rafay also discovered a redirection vulnerability in Facebook.

A Security Researcher from India, Girish Shrimali has discovered Cross site scripting vulnerability in the official website of an Indian scientist and administrator who served as the 11th President of India, A. P. J. Abdul Kalam.

A grey-hat hacker has discovered Critical SQL injection and cross site scripting vulnerability in the official website of The U.S. Navy (navy.mil).

"Recently I was pentesting one of navy.mil subdomains and found serious sql injection that allowed me to extract sensitive data from website database.Sql injection is located in post parameters of a form value.Attacker just needs to craft valid query and submit it to the server." the hacker wrote in an email.

SQLi vulnerability

He also discovered two xss vulnerabillites located on same subdomain , one is post xss and other is get xss , both reflective

"I have reported this to website security and I hope it will be resolved soon.After the fix I will disclose link locations on my blog http://m4x0n3.blogspot.com/." hacker said.

The well-known hacker group NullCrew has discovered a non-persistent Cross Site scripting(XSS) vulnerability in official website of MasterCard. The subdomain "Mobile Payments Readiness(mobilereadiness.mastercard.com) found to be vulnerable to XSS attack.

Usually , the Non-persistent or reflected XSS are considered as low risk. Even thought the risk level is estimated as low, the attackers can steal user accounts by social engineering attack.

For instance , A hacker can redirect victim to malicious or phishing sites by injecting redirection script in the url. I have tested the redirection script,Successfully it redirects me to another site.

The above script redirects to google. An attacker can send the crafted-link and lure users into believe they are visiting legitimate master card site. But, in fact, they are being redirected to malicious site.

NullCrew has also discovered XSS vulnerability on the Department of Homeland Security.

A Security researcher, Riyaz Ahemed Walikar, has posted evidence of a serious persistent Cross Site Scripting(XSS) vulnerability on Tumblr, the popular microblogging platform.

XSS flaws are highly common on websites these days, but most of them are non-persistent and implicitly less dangerous.

"XSS can cause a lot of serious problems. An attacker can steal cookies, redirect users to fake or malicious sites, control a user's browser using automated frameworks like BeEF and download and execute exploits on the victim's computer," Researcher said in the blog post.

"Stored XSS is even more dangerous since the script is stored on the server and is executed everytime user visits an infected page."

Researcher found vulnerability on the 'Register Application' page at http://www.tumblr.com/oauth/apps. The application was not sanitizing user input when a user would create a new application. An XSS attack vector like tester "><img src='x' onerror="alert(document.cookie)"/> would trigger an alert box, displaying the user's cookie, in the browser.

Tumblr were notified more than three weeks ago on the issue. Finally, they fixed the vulnerability Today(july 14).

A security Researcher , Gambit, has discovered Cross site scripting vulnerability in Microsoft official website.

He found the vulnerability last month and reported the vulnerabilities to the Microsoft.

"Well last month I was looking around on MSN.com and Microsoft.com I found two XSS vulnerabilities, one in each domain. I reported the vulnerabilities to the Microsoft security team and secured a spot on their acknowledgments page."Gambit said in his blog.

Microsoft listed his name in the 'Security Researcher Acknowledgments for Microsoft Online Services' page.

'asia.perf.glbdns.microsoft.com' page is vulnerable to XSS. Researcher managed to execute the XSS code in the page.

The third security issue is very intersting persistent XSS. He discovered that there was a way for an attacker to get access to several key pieces of information in the URLs that Gmail generates when it displays a message to a user.

When a message is displayed directly, rather than as part of a user's inbox, it contains both a static user ID and an identifier for the individual message. Those values shouldn't be available to an attacker, but Juenemann found that he could get them through referrer leaks.

"An attacker doesn't know the ik and the message id . Without both values it's not possible to generate the special URL. But it's easy to get both values through referer leaking.

When the user opens the email message, the GIF image will send the user ID and message ID to theattacker's server. The second URL also will leak that data if the user clicks on it. The script will then display a Javascript alert, and that's the attacker's code runningin the context of Gmail.

Akshay AKA 0z0n3 claimed that he have discovered a Persistent XSS vulnerability in blogspot.com. He managed to inject the xss vector in his own blogger dashboard. He is sure it is not template page(usually templates allow bloggers to inject scripts ).

He used one of the following xss vector:
';alert(String.fromCharCode(88,83,83))//\';alert(String.fromCharCode(88,83,83))//";alert(String.fromCharCode(88,83,83))//\";alert(String.fromCharCode(88,83,83))//--></SCRIPT>">'><SCRIPT>alert(String.fromCharCode(88,83,83))</SCRIPT>

<IMG """><SCRIPT>alert("XSS")</SCRIPT>">

After injecting, he didn't get a pop-up but after some minutes he started getting pop-ups. He reported about the vulnerability to Google Security team. The vulnerability is not rewarded by Google.

"Thank you for your note. We took a look at the XSS issue you reported. Unfortunatley, the XSS issues is executing on the blogspot domain and not blogger.com. We come some of these scenarios here.

Unfortunately, XSS issues on blogspot(as opposed to blogger.com) do not quailfy for the VRP. If you manage to execute this javascript on someone else's blog or on the blogger.com domain, that would qualify for a reward." Google response mail.
